Note: If your Big Bear 88NT engine is experiencing coolant temperature gauge cycling, replace your existing thermostat with this Cummins 3064454 173 degree thermostat. The new Cummins 3064454 thermostat provides a slower coolant response rate to reduce dramatic engine temperature cycling. This slower engine response rate does not affect the engine performance.

The Cummins 3064454 Thermostat on your Big Bear 88NT Cummins engine allows low-temperature coolant from the radiator into the engine to keep the operating temperature within a predetermined range. Operating a Cummins engine with a bad thermostat will cause the thermostat to get stuck in the open or closed position. A defective thermostat will cause the engine to operate either below the correct operating temperature or above it leading to an overheat condition. If you are currently experiencing any of these symptoms, it's time to replace the Cummins 173 degree thermostat to alleviate this issue.
